I sent my unicorn on a quest (as part of the tutorial). He just came off the quest. Shortly after starting his quest, I sent my dragon on one. She's still showing 10 minutes left as of right now. But 20 minutes ago (30 minutes left), she started being labeled as Active and I even used her to explore. That's not right, is it? (It was the "Dragon needed to appraise gold" quest, if that matters.)

Edit: I grabbed a screenshot where you can see she is both Active and has a quest listed under Effects. http://i.imgur.com/UYNgHUr.png

Thank you for reporting!

You're right, this is a bug. We will try to fix it as soon as possible.

Sorry for the inconvenience.
